`Application fild May 1, 1922. Serial No. 557,593.

To aZZ 'whom t may concern:

Be it known that I, JOHN a citizen o-f the United States ofAmerica, a resident of the city of St. Louis, in' the State of Missouri, have invented certain new and useful Improvements in Seals, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification; f

This ,invention relates to improvements in seals, and particularly to'devioes of this character which may be applied without the use of tools to freight cars to l'ockthe doors thereof and which, when applied,,cannot be removed without breaking or destroying the seal.

A still yfurther object is to provide a seal of simple and inexpensive construction which is formed entirely of a single strip of metal and is provided with reinforcing means whereby the strip of' metal of which said seal is formed may withstand' the strains to which it is subjected.

'With the foregoing and other objects, in view,"the invention comprises the novel, construction, combination and arrangementof parts hereinafter more specifically described and illustrated in the raccompanying drawings wherein is shown the preferred embodiment of the invention. However, it vis to be understood that the invention comprehends changes, variations and modifications which come within the scope of the claims hereunto appended.

The strip A comprises 1a Ibody porftion'YB and a shackle-forming tongue C.

A portion ofthe body portion B is struck up Vto forml a raisedjkeeper 1, and extended ,throughV said body at one end of the keeper lis a'transverse opening. o

. VInfor1 ning the seal'frompjthe strip. A, I .bendthe 'body portion of the stripV on a transverse-line a vcontiguous to the opening 2, andv fold what-Itermthe catch section 8 rearwardly against the keeper section 4:. I then fold the body. Bona-line Z) to' form a rear guard section 5, which lies against vthe back of and protects the intermediate .catch section 3. v The several Sections 3, 4

and 5 are 'secured to each otherin any suitable manner-after'V the folds have been made,

and as a most'economical means of fasten- 'ing said Sections, I punch 'holes 6 through the several sections and upset the spurs produced bythe punching Voperation to' form rivet members 7 (Fig. III). The holes just referred Vto are preferably jformed so that they extend through the 'keeper section 4 at opposte sides ofjthe`keeper 1, as seen in Fig. III, and therefrom through the sections .2 and 3.

In forming the seal strip I strike a tang 8, which is so disposed'that it lies in the catch section 3 and Projects forwardly from said section when the body of the strip is folded, as explained, and lies within the keeper 1 of the keepersection 4:, as seen in i'Fig. VI. Torreinforce the tang 8 so that it may be better` able to withstand strain to which itfmay be'subjected, I provide said tang with aV reinforcing [rb ``9,` which Qngtndinally of Sadtang' AlSO th'getongue .of thestrip is' bowed into shackle :form and inserted through the `keeper 1 fofthe keeprzsecttioa 34h Adjacnt to each w To prevent the tongue of the strip fromV being weakened because of the absence of the metal which is removed to produce the apertures 10, I arrange reinforcing members 12 which eXtend around said' apertures on three sides thereof, saidkreinforcing portions being in the form yofV ,U-sh'a'ped ribs pressed outwardly from the body of the tongue.

When the'body of the seal hasbeen folded to produce the sections 3, 4 and 5, the tongue of the seal extends rearwardly from the keeper section 4, and in putting the seal'in service it is only necessary to loop the tongue C so that its end may be inserted through the opening 2 and through the keeper 1, where it will be interposed between the section 3 and the section 4 of the body portion B (Fig. IV). In so doing I' provide a shackle formed from the tongue C, said tongue extending through the keeper 1 and between the front of the keeper and the portion of the catch section 3 immediately back of the front of the keeper and which is occupied by the tang 8. In inserting the tongue of the seal through the keeper 1, the tongue traverses Vthe tang 8, land upon any attempt to withdraw the tongue from said keeper, the tang 8 enters into one of the apertures 9 and prevents the withdraWal of said tongue. By providing the flexible extensions 11 an additional grip is obtained between the tang 8 and tongue C, as said flexible extensions 11V may' be drawn into closer contact with and conform to the Shape of the tang than if said tang contacted with a rigid portion of said tongue. The tongue is therefore so gripped as to be securely held against backward movement, with the result of efectually preventing the opening of the seal.

I preferably provide a number of apertures 10 in the tongue C in order that a larger or smaller shackle may be provided, asA may be desired or required.

I claim:

1. A seal comprising a strip having a body formed and folded to provide a keeper section and a catch section, lying one in front of the other, a tongue extending from said body, said tongue being provided with apertures, said keeper section being provided With a keeper and said catch section being provided with a tang extending into said keeper, said tang being adapted to enter an aperture in said tongue when the latter is said keeper, said tang being adapted to enter an aperture in said tongue when the latter is inserted into said keeper, and U-shaped reinforcing means on said tongue adjacent to said apertures. f
